Unable to perform collectstatic
Solution 1:
Try this,
PROJECT_DIR = os.path.dirname(os.path.abspath(__file__))
STATIC_ROOT = os.path.join(PROJECT_DIR, 'static')
Look at https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-STATIC_ROOT
Solution 2:
You must have to give path in STATIC_ROOT in settings.py where all your static files are collected as for example:-
STATIC_ROOT = "app-root/repo/wsgi/static"
STATIC_URL = '/static/'
STATICFILES_DIRS = (
('assets', 'app-root/repo/wsgi/openshift/static'),
)
